Where is the ADC10_A channel # A12 mapped to? or how?
I could not find it in MSP430x5xx/MSP430x6xx FamilyUser's Guide (SLAU208J), nor in the MSP430 Datasheet of MSP430F550x
thx for reply
Take another look at the datasheet. Especially Table 1: Family members. In teh ADC10 column, you'll only find members with 6 or 10 external channels. So only A0 to A9 are externall mapped. A10 and A11 are internal and the rest is simply not present.
Time to say goodbye - I don't have the time anymore to read and answer forum posts. See my bio for details.Before posting bug reports or ask for help, do at least quick scan over this article. It applies to any kind of problem reporting. On any forum. And/or look here.I'm sorry that I can no longer provide help in the forum or by private conversation.

Thanks for reply.
There was a mistake in my queston, I am interested in the internal channel #11, which is only shown in slau208j Figure 25-1. ADC10_A Block Diagram. The channel is assigned to Batt.Monitor. I should know what it is exactly, because there are multiple supply pins on the chip. And how it is assigned (e.g. resistor divider). I could not find more about this channel. Does somebody know more?
thanks for reply
In reply to christ hassler:
Soem MSPs have a backup battery module. There a BAKADC bit can be set and will route Vbatt/2 to the ADC. So you can measure the state of the backup battery.On ADC12, channel 11 usually reads VCC/2.
I don't know whether there is actually an MSP with battery backup and ADC12.
It is possible that on MSPs without battery backup system, channel 11 of the ADC10 also reads VCC/2.
